The US-China AI Fight Is Becoming a Trade Battle
Matthew Leo · Published July 27, 2026 · AI
The fight over whether Chinese AI companies copied American models is escaping the laboratory and entering trade policy.
China’s commerce ministry accused the United States of “AI hegemonism” on July 27 and warned that it could take countermeasures if Washington imposes sanctions or technology restrictions on Chinese AI companies.
The immediate dispute centres on Moonshot AI and its Kimi K3 model. US officials allege that Moonshot used large-scale distillation to reproduce capabilities from Anthropic’s Claude models. Moonshot denies that Kimi K3’s improvements came from that process.
Distillation is not automatically theft
Model distillation generally involves using outputs from a more capable model to train or improve another system. It is a common machine-learning technique.
The disagreement is about scale, access and authorization. American officials say coordinated extraction through fraudulent accounts can cross the line from ordinary development into intellectual-property theft.
Anthropic said in February that it identified more than 3.4 million exchanges associated with Moonshot across hundreds of accounts. The company said the activity targeted reasoning, coding, data analysis, computer use and vision capabilities.
That is Anthropic’s attribution. It has not been established in court that Moonshot stole a model or that Kimi K3 was created from those exchanges.
Washington is considering heavier tools
According to Reuters, White House science and technology director Michael Kratsios said the US government had information indicating that Moonshot distilled Claude Fable 5 while developing Kimi K3.
Treasury Secretary Scott Bessent subsequently said financial sanctions and placement on the Commerce Department’s Entity List could be considered when industrial-scale distillation amounts to intellectual-property theft.

No such sanction against Moonshot had been announced when this article was prepared.
Moonshot told Chinese media that Kimi K3’s performance resulted from original architectural changes. China’s commerce ministry said the American threats lacked factual and legal grounds and promised to defend Chinese interests if restrictions caused substantive harm.
The dangerous part is the policy precedent
Sanctions would turn a technical and contractual dispute into another front in the semiconductor trade war. An Entity List designation can restrict access to American chips, software, cloud services and other technology.
The United States should be able to investigate coordinated account abuse. It should also present evidence before treating competitive model performance as proof of theft.
China’s blanket dismissal is equally convenient. If companies used deceptive access methods at the scale Anthropic describes, calling every response “hegemonism” does not answer the underlying evidence.
The facts must now catch up with the threats. Until they do, the distillation claim remains serious, consequential—and disputed.
